Case overview
The Watermark Office and Business Suite faced 10 to 12 significant leaks, making it one of the most challenging projects to date. The roof substrate was in extremely poor condition due to previous unsuccessful repairs, which included the application of liquid waterproofing with matting that had deteriorated over time.
Project Overview
- Client: The Watermark by Wrkspace
- Location: Preston, UK
- Project Size: 450m²
- Date: September 2024
- Duration: 5 Days
- Roofing System: Overlay repair of heavily compromised substrate


The Solution:
Rubber Roofing Supplies NorthWest (RRSNW) referred their trained roofing contractors to carry out the installation, using PeelAffix20 self-adhesive EPDM membranes to tackle the severe substrate issues and restore the roof’s integrity.
PeelAffix20 was chosen for its:
- Superior Adhesion: The self-adhesive backing bonded securely to the difficult substrate, providing a seamless, watertight layer.
- Exceptional Durability: Its self-adhesive backing eliminates the need for additional adhesives or primers, making it perfect for overlaying existing roof systems.
- Cost Efficiency: At a fraction of the cost of a full roof replacement, PeelAffix20 provided a high-performance solution without compromising quality.




The Process:
- Preparation: The severely degraded substrate was cleaned and stabilized to allow for proper bonding. Areas with previous liquid waterproofing and matting were inspected and reinforced where necessary.
- Application: The 450m² roof area was overlayed with PeelAffix20, ensuring precise placement and sealing all joints and overlaps to create a durable watertight barrier.
- Completion: Within 5 days, the project was completed, leaving the roof completely leak-free and ready to withstand the elements for decades to come.
